Manufacturer: | Categories: ,

The NovAtel G3Ant-42A4T1 is a multi-frequency active GNSS antenna with a mini-ARINC footprint for GPS/GLONASS L1 and Galileo E1.



The NovAtel G3Ant-4AT1 mini-ARINC GNSS antenna is part of the G3Ant-42XXX product family of multi-frequency GNSS antennas. This Antcom “G3” antenna operates in three frequency bands and includes support for GLONASS L1, GPS L1 and L-Band. The baseplate is designed to be compatible with ARINC 743 mounting hole and footprint requirements. An O-ring seal between the antenna and your platform ensures easy installation.

The product family is offered in passive and active (amplified) configurations. The active configurations offer 2-stage integrated bandpass filtering for high out-of-band rejection and limiter diodes to protect sensitive receiver electronics. The passive configurations are best suited for applications where the antenna is located close to the GNSS receiver. It offers the lowest insertion loss for minimizing the noise figure of your system.
